6 Claims.

This invention relates to ophthalmic mountings and more particularly hasreference to a bridge for an eyeglass or spectacle.

One of the objects of this invention is to provide an improved bridgemember for an ophthalmic mounting which will be relatively simple instructure, yet neat in appearance and efiicient in operatic-n. Anotherobject is to provide means whereby adjustments may be made on aresilient bridge element whose ends contact the edges of the lenses. Afurther object is to provide a resilient bridge which will be relativelyinconspicuous. These and other objects and. advantages reside incertain. novel features of construction, arrangement and combination ofparts as will hereinafter be more fully disclosed and pointed out in theappended claims.

Referring to the drawing:

Fig. 1 is a front view of an eyeglass embodying my invention.

Fig. 2 is an enlarged fragmentary top plan view thereof.

Fig. 3 is a view taken. on line 3-3 of Fig. 1.

Fig. 4 is a fragmentary rear view of the bridge.

One embodiment of my invention is shown in the drawing wherein Hiindicates an eyeglass having the two lenses ll connected by a bridgeindicated generally at l2. The bridge comprises a substantially fiatresilient element [3 which extends tangentially along the top edges ofthe lenses l l with its two ends respectively in contact therewith.Secured to the nasal edge of each lens H by any suitable means, such asa screw, cement or molded rivet, is a strap M which carries a.rearwardly extending arm l5 supporting a nose engaging element or padIt. A member l'l, hav- :ing one end secured to the arm I5, at itsjunction with strap l extends upwardly and outwardly along the peripheryof the rear face of the lens to a point adjacent the top edge of thelens where it is secured, as by soldering, to the end of element l3. Themembers ll are preferably resilient and they lie in a plane which isspaced rearwardly from the plane of the lenses.

In operation, the lenses I! are grasped, one in each hand, and turned soas to flex the spring element l3 and separate the pads IE to receive thenose of the wearer. The two ends of the resilient element l3 are incontact with the upper edges of the lenses and the spring I3 flexes atthe intermediate portion. In case the mounting is accidentally bent sothat the ends of spring l3 are thrown out of engagement with the upperedges of the lenses, they may be returned to their proper positions bygrasping the members 11, attached to element l3, with pliers and mak ingthe necessary adjustments. The members 17 are spaced behind the lensesand they extend upwardly from the lens holding strap I4 along theperiphery of the lens so that they are hardly visible from the front ofthe eyeglasses. This renders the mounting quite inconspicuous.

From the foregoing it will be apparent that I am able to attain theobjects of my invention and provide an improved eyeglass mounting whichwill be simple in structure and present a neat appearance. Variousmodifications may be made without departing from the spirit of myinvention as pointed out in the appended claims.

I claim:

1. An ophthalmic mounting comprising a pair of lenses, a lens holdingdevice secured to the nasal edge of each lens, a nose pad carried byeach of said devices, a member carried by each device and extendingupwardly and substantially following the contour of the lens to a pointadjacent the top edge of the lens, said members being spaced rearwardlyfrom the rear faces of the lenses, and a resilient bridge element andmeans connecting the two upper ends of said members to said element, theend portions of said element being in contact, respectively, with theupper edges of the lenses.

2. An ophthalmic mounting comprising a pair of lenses, a lens holdingdevice secured to each of said lenses, an arm secured to each of saiddevices and extending rearwardly therefrom, a nose pad carried by eacharm, a resilient member secured to each of said arms and extendingupwardly therefrom along the edge of the lens, each of said memberslying in a plane which is positioned rearwardly of the lenses, and aresilient bridge element and means connecting the two upper ends of saidmembers to the respective ends of said element, the two ends of saidelement being in contact, respectively, with the upper edges of thelenses.

3. An ophthalmic mounting comprising a pair of lenses, a lens holdingdevice secured to each lens, a nose engaging element carried by eachdevice, a member carried by each device, said members being positionedin a plane which is spaced rearwardly from the plane of the lenses, eachof said members extending upwardly and outwardly from a point adjacentthe nasal edge of the lens and substantially following the contour ofthe lens, and a resilient bridge element, and means connecting the upperends of said members to the respective ends of said element,

ill

said bridge lying substantially in the plane of said lenses.

4. An ophthalmic mounting comprising a pair of lenses, a lens holdingdevice secured to the nasal edge of each lens, a nose pad carried byeach device, a resilient member secured to each device and extendingupwardly and outwardly along the periphery of the rear face of the lens,said members being positioned in a plane which is spaced rearwardly fromthe plane of the lenses, and a resilient bridge element extending intangential relation along the upper edges of the lenses, and connectingmeans whereby the upper ends of said members are attached, respectively,to the two ends of said element, the two ends of said element being in.contact with the upper edges of the respective lenses.

5. An ophthalmic mounting comprising a pair of lenses, a lens holdingdevice secured to the nasal edge of each lens, a nose-engaging elementcarried by each device, a member carried by each device, said membersbeing positioned in a plane which is spaced rearwardly from the plane ofthe lenses, each of said members extending upwardly and outwardly from apoint adjacent the nasal edge of the lens and substantially followingthe contour of the lens, a resilient bridge element and laterallyextending means connecting said members to the respective ends. of saidbridge element, said bridge element lying substantially in the plane ofthe lenses with its ends contacting, respectively, the upper edges ofthe lenses.

6. An ophthalmic mounting comprising a pair of lenses, a lens holdingdevice secured to the nasal edge of each of said lenses, an arm securedto each device and extending rearwardly therefrom, a nose-engaging padcarried by each arm, a member carried by each device and extendingupwardly and outwardly therefrom and substantially following the contourof the lens, each of the members lying in a plane which is spacedrearwardly of the lenses, a resilient bridge element and laterallyextending means connecting said members to the respective ends of saidelement, the two ends of said element being in contact, respectively,with the upper edges of the lenses.
